Title: Improvements in filters for liquids
IPC: B01D29/46
Filed: 1933-02-07
Abstract: 414,749. Filters. SIMMS MOTOR UNITS, Ltd., Percy Buildings, Gresse Street, London, and ATTWOOD, S. H., Chenies, South Lane, New Malden, Surrey. Feb. 7, 1933, No. 3736. [Class 46.] In a filter in which the liquid flows from one passage to another through a relatively narrow elongated filtering space or spaces each formed between the edges, or one such edge and a surface, of adjacently arranged elements, the filtering edges are vertically disposed and the liquid is so led thereto that, upon the entry side of the filtering spaces, it flows downwardly along the whole of said edges towards a sump or other receptacle, thus tending to convey particles of dirt restrained by the edges downwardly to the sump. The filter shown comprises an outer cylindrical casing 4 and an inner core 6 between which a sleeve 7 is located provided internally and externally with a series of longitudinal V-section grooves, which sleeve is a close fit at each end of the casing 4, but which has the apices of the groove walls reduced for the greater portion of their length to provide narrow filtering spaces 10, 11 of about .005 and .002 inches cross section on the inside and outside respectively of the sleeve 7. The upper and lower ends of the sleeve 7 are closed by rings 13, 14 which provide communication with alternate grooves of the sleeve. The liquid to be filtered enters by the pipe 2 under a few pounds pressure or with suction and flows down the grooves 8 towards an inner sump 20, it then filters through the spaces 11 into the grooves 8<a> and passes through passages 12 into the grooves 9 which are in communication with the outer sump 21. The liquid is again filtered through the spaces 10 into the grooves 9<a> up which it rises and passes off through the outlet 3. The sumps 20, 21 may be removed for cleaning by unfastening the nuts 24<a>, 24. The sleeve 7 may be moulded from synthetic resin in which case the rings 13, 14 may be formed integral therewith. The filter may be mounted on the dashboard of a road vehicle so as to be slightly vibrated.

Title: Improvements in or relating to electric condensers
IPC: H01G4/258
Filed: 1938-02-09
Abstract: 511,042. Condensers. DUBILIER CONDENSER CO. (1925), Ltd., and MOORE, N. C. Feb. 9, 1938, No. 4064. [Class 37] A plate of insulating material is mounted so as to be moved rectilinearly across another, each plate bearing metallic layer electrodes, one or both of which being of strip form with the separate strips mounted transversely to the line of movement. Additionally, the plate or base may be built up of strips of dielectric materials of different capacity-temperature characteristics. In the example, Fig. 3, a variable condenser comprises strip electrodes C, E, borne respectively by plates A, B, the plate B constituting the dielectric. Fig 5 shows a condenser of fixed capacity, the movable dielectric plate being constituted by strips H, H\ of differing capacity-temperature characteristics, and of thickness corresponding inversely to their dielectric constant. The electrode C borne by the base A is in strip form, while that, J, borne by the moving plate, is continuous, as shown, but may be also in strip form, the strips of dielectric being of unequal width and each strip having part only of its surface covered by an electrode layer J. A condenser is also described of variable capacity and of fixed capacity-temperature coefficient employing a dielectric with strips of unequal width and strip electrodes mounted on the movable plate and the base. The movable plate may be caused to move over the base in any of these forms by means of a disc with pin and slot connections or by means of an arm mounted on one side with a depending pin engaging a recess in the moving plate.

Title: Improvements relating to gas generators and the like
IPC: C10J1/213
Filed: 1926-02-12
Abstract: 270,429. Patent Retorts, Ltd., and Davidson, T. M. Feb. 12, 1926. Producers.-A pair of water gas generators each has flues connecting the lower end of the combustion chamber of each generator and the top of the preliminary distillation retort of the other generator. The generators a, a<1>, with corresponding retorts a<2>, a<3>, may be disposed in the same setting b. Each has a space a<5> below the grate with an air inlet a<6> and gas offtake a<7> (Fig. 7). Each generator communicates at its upper end through a passage d<1> with one of two flues d, which are disposed between the generators and have a passage d<4> at their lower end, which may be closed by a flap or other valve, communicating with the other generator. Or external pipes extending directly crosswise from the top of one retort to the space beneath the other generator may replace the flues. Both generators may be filled with coke and the retorts with coal. After ignition, air is introduced into both generators and combustion products pass through radial passages a' into an annular flue a<12> containing chequered brickwork and thence into an outlet a<16> having a " snift " valve a<17>. Secondary air is admitted through an annular flue c. If gas rich in hydrogen and free from condensable hydrocarbons is required, the blast to one generator is shut off when the charge is sufficiently hot to produce water gas in a making period of 2 minutes or less, and the passage to a vertical flue is opened and the gas offtake of this generator closed. The gas passes through the flue into the top of the other retort and through the charge to the offake a'. After 3¢ minutes the gas direction may be reversed for another 3¢ minutes and the cycle repeated. Or the gas may continue in one direction for the whole of the making period of a cycle. Steam is admitted during the making period into both pipes a<16> and is superheated in flues a<12>. When complete cracking of the hydrocarbons is not required, the gas flow may be through the fuel bed of one generator, a vertical flue, the retort charge of the other generator and thence through the passages a' and a<1> to a top gas outlet valve a<18>.

Abstract: 539,246. Motor controllers. RAMSDEN, H. K.. KETTLEWELL, H .N. W.; and METROPOLITANVICKERS ELECTRICAL CO.. Ltd. March 8, 1940. Nos. 4402 and 10110. [Class 38 (iii)] A lever 8 actuating the controller of a trolley bus is operated by a pedal 9 through a spring link 12 and is retarded by a piston 4 working in a cylinder containing oil. Until the motor current reaches normal accelerating value, a valve 26 is open and controller moves freely. After the valve 26 is closed the controller is moved slowly. When the motor current reaches an upper limit valve 19 closes and the controller then only advances very slowly, this advance allowing the motor to accelerate on hills. Quick return of the controller is permitted by the valve 24. To prevent the valve 26 closing due to heavy regenerative current, a polarizing coil 45 can be fitted thereon. To adjust the setting of the valve 19 according to field current it is controlled by a relay 37 subjected to both armature and field current.

Patent GB-398801-A (GB)
Title: Improvements in or relating to the manufacture of cellulose or cellulosic materials
IPC: D21C3/00
Filed: 1932-02-16
Abstract: Cellulose in a form particularly suitable for esterification, is obtained from wood, straw, grass, or other lignified cellulose material, by separating the non-cellulosic constituents therefrom by means of a liquid comprising a glycol, e.g. ethylene glycol, propylene glycol, or trimethylene glycol.  An aqueous solution of the glycol containing between 30 and 80 per cent of water may be employed at elevated temperatures, for example, from 120 to 180 DEG  C. Increased pressure, if required, may be obtained by working in an autoclave and introducing an inert gas under pressure, e.g. carbon dioxide, or nitrogen, or else a low boiling liquid, such as methyl alcohol, ethyl alcohol, benzol, or petroleum ether.  The cellulosic materials may be subjected to a prior or simultaneous treatment, for example, with dilute alkali or the usual liquors, to remove resins, lignins, or the like.  In an example, mechanical spruce pulp is subjected in a closed digester to reduced pressure, and an aqueous solution of ethylene glycol is run in.  The treatment is carried out for six hours at 160 DEG  C., after which the cellulose is removed and washed.  The Provisional Specification refers to the use of alcohols of high boiling-point in general, and specifies also glycerol.
